ES 1.0 Graveyard

Thank you for these insight to my problem and the suggestions for investigations. I'll test that and hopefully find out the origin of the issue (fingers crossed). I have already removed a dodgy connection from the system and detached the controller from the frame (it's now hanging in a bag). Next st...

Thanks for this suggestion amberwolf. I did the check and evrything seems fine. I also tested the throttle and the pedal sensor and both trigger a response and make the hub turn. As I said, I only get this fault when I connect the -tive side of the battery to the bike frame. Besides the issue with m...

.. I connected the -ve side of the battery to the frame. And now as soon as press the throttle, I have a fault with the phaserunner. It says "Fault 9 Instantaneous phase over current"... Anyone who could help ? I did what is suggested on Grintech site with no positive effect. " Insta...

Hello, I read this thread because I have a similar issue with my set up. I connected the -ve side of the battery to the frame. And now as soon as press the throttle, I have a fault with the phaserunner. It says "Fault 9 Instantaneous phase over current". Did I do something wrong on the wir...

I simply cut the BSA threadened bottom bracket tube from a scrap frame and pressed it into the press fit frame
OK, I needed a lathe to get the outside diameter to the right size.

I really like the idea

BB I've seen some torque sensing bottom brackets that fit into standard 68/73 and 100mm shells, so figure that an adapter that works with the bafang motors, that fit the same style bottom bracket, would work for installing one of them. Maybe not, but seems like with the adapters, the 100mm sensor m...

There's a collection of infos about various torquesensors in the german Pedelecforum wiki: https://www.pedelecforum.de/wiki/doku.php?id=elektrotechnik:drehmomentsensoren You can use google translate. My suggestion is the Phoebe Liu Shop at aliexpress: https://phoebeevparts.de.aliexpress.com/store/g...

I do not have additional information. The question is « are there any Bottom Bracket torque sensor for BB86 ? » You probably read through this post; couldn't tell if the adapter for the BB86 also works for the BB92: https://www.empoweredcycles.com/blogs/news/101474694-bottom-bracket-standards-and-b...

Grintech might have an answer. I order my equipments from them most of the time and they currently don't sell what I need. For the moment, I am asking here. :wink: I couldn't find anything using google either so I am hoping others might have done the same research more successfully or might have the...

Looking for answers to my current problem, I found this discussion and I find the title quite suitable. I hope it's Ok if I use it :-) I am investigating the possibility to electrify a gravel bike with a "large" bottom bracket cups. Do you know if any BB torque sensor for BB standards like...

The dealer who sold me the hub and the spokes told me not to worry too much about it too. There is a shortage with the e-Strong Sapim spokes and so I will wait a while and check the state of my wheel regulary.
I have been riding approx 50 km with it with no signs of weakness in the wheel so far.

I have built a new wheel with a RH212 9C motor and since then, I have no issues at all with the dislay screen. I believe the problem was coming from the GMAC motor.

Thanks ZeroEm, yes, I think I will rebuild it with a new set of spokes. It should look like the picture below. The current build is worrying me too much.

I have juste finished building a 700C wheel with a RH212 hub motor and Sapim e-strong spokes. The way the spoke bends just after the nipple makes me a bit nervous. Is it acceptable to have such small bent? The spoke angle is a bit more than 70 degree so I thought it would be OK. The nipples though a...

The baserunner sits in the battery bag, yes. That's why I separated them for a test. But it didn't help.
Yesterday I dit another 50 km without any issue on the display and no explanations, besides maybe the new cable routing.

So I wont solder the capacitors in the CA for now.

Yesterday, I did a test trying to remove all possible loop in the wiring of all components. I moved my battery from its current place into a bigger rack bag. And the problem was still there. So I put my battery in its usual battery bag below the seat, I kept the new cable routing though. Did a new t...

So to get this thread hopefully moving along i'll throw out a question based on the following 72V 6P pack using 18650 Sanyo GA cells ... https://litespeedbikes.mybigcommerce.com/72v-21ah-triangle-battery/ Can your design effectively be just as efficient as the above fabrication if it were also 5P l...

I have a procedure to disconnect the button pins cable inside the CA and see if this isolate the problem.

I disconnected the CA buttons and indeed the issue remains. It's definitely related to induced noise from the system (battery or engine).

Zorbas, I may be having some success against a related (but different) problem by simply grounding the negative terminal of the battery against the frame. Suggest you try that. Wow! I am not familiar with that technique and have basic understanding of electrical systems but after a quick search I h...

Oh yes! Good point. I messed up the configuration of the 20S2P I illustrated a 20S30P here. I will correct that.
But otherwise ? Is it realistic to build these shapes?

I want to use it for a GMAC 10T with Phaserunner or maybe later with a RH212STD

Hello, this is my first DIY battery. I have two configurations that I'd like to consider but I am not quite sure it it is realistic/feasible. Can you tell me if this is easily achievable? I want easy series and parallel soldering (with a spot welder). I am considering using diagonal plastic spacers ...

I have a reply from GrinTech. Apparently it could be related to induce noise from the GMAC motor and disturbing specific CA controls. I am not an isolated case apparently. My particular issue could be related to noise into the CA buttons/switch. I have a procedure to disconnect the button pins cable...

I did some additional check today. It seems to be related the some kind of interference between the engine and the CA.

Does that make sense?

I guessing it's some type of connection not maintaining contact but not losing it completely. Have you looked at the battery to baserunner connection. Just a wild thought. This one maybe hard to find or not what we think. I did the check, removed and replaced the connectors. In order to isolate the...
